prcuaIT Posted June 14, 2023 ID:1572482 Share Posted June 14, 2023 I rolled back the Windows update as suggested on a Windows Forum and that was a good temp fix for one of my clients that could not access MB Endpoint settings. Link to post Share on other sites More sharing options...
Iadcr Posted June 14, 2023 ID:1572491 Share Posted June 14, 2023 Is there any workaround for the Nebula Agents until a patch is released? Thanks! 1 Link to post Share on other sites More sharing options...

FYI, As I posted above, rolling back the Windows update worked for me, while helping a client. I tried to login to the normal MB endpoint cloud to see if I could turn off MB for Chrome, but could not get past the "Now you must use Nebula" popup. I could see the Endpoint dashboard behind the popup, but the Nebula login popup always responded with "your session has timed" out when I attempted to log in. Was glad that the Win Update rollback worked. Link to post Share on other sites More sharing options...

ac513 Posted June 14, 2023 ID:1572540 Share Posted June 14, 2023 Interestingly, I am an admin of a university that is a Cisco Secure Endpoint shop. We're seeing this exact same behavior as well with the June 2023 cumulative updates, and my initial testing has narrowed it down to Secure Endpoint's "Exploit Prevention" engine being the common denominator causing the problem with Chrome not opening. It seems like Malwarebytes' analogue exploit engine is the cause of this on yall's side, so there has to be more to this story. The latest Windows update specifically reference possible issues with security applications. I don't know if it's coincidence or relevant, though. https://support.microsoft.com/en-us/topic/june-13-2023-kb5027231-os-build-22621-1848-8f903600-1293-4431-9c6b-736a4049666c Quote This update addresses a known issue that affects 32-bit apps that are large address aware and use the CopyFile API. You might have issues when you save, copy, or attach files. If you use some commercial or enterprise security software that uses extended file attributes, this issue will likely affect you. For Microsoft Office apps, this issue only affects the 32-bit versions. You might receive the error, "Document not saved." 1 Link to post Share on other sites More sharing options...

khawker Posted June 15, 2023 ID:1572632 Share Posted June 15, 2023 It is not issue in Malwarebytes only. We had this issue while using ESET Protect. Basically, you cannot open chrome after update IF you have any other chromium based browser (so edge as well) set as your default browser. Using chrome or something like firefox as default fixes issue. 2 Link to post Share on other sites More sharing options...
Iadcr Posted June 15, 2023 ID:1572658 Share Posted June 15, 2023 I just read this on the support page: Quote Resolution To mitigate this issue and prevent Google Chrome from crashing, we've applied an update which disabled Google Chrome as a protected application in your policy settings. Once this issue is resolved, Google Chrome will be added back as a protected application in your policy settings. Is this saying that chrome is vulnerable to attack right now for all of my clients!? This would be unacceptable to shut down protection for all of my clients who use Chrome when the small % who are affected could just use Edge safely temporarily. Please let me know if I'm misunderstanding this. 1 Link to post Share on other sites More sharing options...
Staff H4V0C Posted June 15, 2023 Staff ID:1572666 Share Posted June 15, 2023 (edited) 23 hours ago, AdamFineLine said: I hope a patch is pushed out by Malwarebytes as soon as possible, our phones have been ringing off the hook all morning with customers calling about not being able to open Google Chrome which is a pretty big problem (considering it's one of the most important apps that a lot of people use because all their passwords and bookmarks are saved within). We plan to push out an update today that will temporarily address this issue until we're able to fully resolve the conflict. We'll keep you posted as the day progresses. 23 hours ago, mnbrightblade said: When you come out with in update, will it automatically enable protection for Chrome again since we had to manually turn it off as a temporary fix? We're still working out the details on this but, in order to get the fix out as soon as possible, we might not be able to re-enable exploit protection for Chrome automatically if it was manually turned off by the user. We're exploring options to see if there is a way to automate that. Worst case scenario, we may need to create a knowledge base article to guide users on re-enabling the protection and share the article or link directly to users. Edit for clarification - this pertains to our Malwarebytes consumer product. Edited June 15, 2023 by H4V0C clarification of product version Link to post Share on other sites More sharing options...

Yes, as a last resort, if we cannot find a way to automatically re-enable protection, the fallback plan is to utilize an app notification that guides the user on how to re-enable their protection.

Staff H4V0C Posted June 15, 2023 Staff ID:1572698 Share Posted June 15, 2023 (edited) 📣 UPDATE 📣 We have released the temporary fix to resolve conflicts with Chrome in Malwarebytes Premium. The temporary fix will automatically disable anti-exploit protection for Chrome as suggested in the knowledge base article we published yesterday. Again, this is only meant to be a temporary fix so that users are able to launch Chrome again. This patch will automatically roll out to users via Update package version 1.0.70914 when the product checks for updates - by default this check is performed on an hourly basis. For devices that get this patch automatically, no further action will be required to restore anti-exploit protection for Chrome once we provide a better long-term fix. For devices where anti-exploit was manually turned off (as instructed in the knowledge base article), no further action is required at this moment. Once the long-term fix is implemented, we'll know whether anti-exploit needs to be manually re-enabled for Chrome.

shruiken15 Posted June 16, 2023 ID:1572884 Share Posted June 16, 2023 So, if Exploit Protection for Chrome is currently turned off, does that mean that it is not secure to browse with Chrome at the moment? I am trying to understand the full scope of the issue, as my work is largely browser-dependent and I rely on being able to use Chrome securely.
